Thamnophilus is a genus of antbird in the antbird family, Thamnophilidae. The species in this genus are commonly known as antshrikes. They are insectivores that feed by gleaning prey from foliage and are found in the Neotropics.

The genus Thamnophilus was introduced by the French ornithologist Louis Pierre Vieillot in 1816. The name combines the Ancient Greek words thamnos "bush" and philos "loving". The type species was subsequently designated as the barred antshrike.
